How to Use the Babylist Pregnancy Calculator

Using the Babylist Pregnancy Calculator is simple:

  1. Enter Your Last Menstrual Period (LMP): This is the first day of your last menstrual cycle.
  2. Optionally Enter Conception Date: If known, input the date of conception for more accurate calculations.
  3. Click Calculate: The calculator will determine your estimated due date (EDD), trimester stages, and week-by-week progress.
  4. Review Results: You’ll see key milestones, trimester changes, and expected dates for prenatal development.

This allows you to plan appointments, monitor growth, and prepare for your baby’s arrival with confidence.

Formula Behind the Babylist Pregnancy Calculator

Pregnancy calculations are based on standard obstetrics formulas:

  • Estimated Due Date (EDD):
    EDD = LMP + 280 days (40 weeks)
  • Gestational Age:
    Gestational Age = Current Date – LMP (in weeks)
  • Trimester Calculation:
    • First Trimester: Weeks 1–12
    • Second Trimester: Weeks 13–26
    • Third Trimester: Weeks 27–40

These calculations provide an accurate timeline of pregnancy progression and milestones.

Example of Using the Babylist Pregnancy Calculator

Scenario:

  • Last Menstrual Period: January 1, 2025

Calculation:

  • Estimated Due Date = January 1, 2025 + 280 days ≈ October 8, 2025
  • Current Gestational Age (as of October 6, 2025) = 40 weeks

Result:
The expected due date is October 8, 2025, and the pregnancy is in the late third trimester, allowing parents to plan final preparations.

This example demonstrates how the calculator provides clear, actionable pregnancy information.
